疲劳及疲劳裂纹扩展速率实验数据由于实验本身、材料、测量误差以及实验条件、环境等因素的影响,使之产生较大的分散性。为了定量地比较其优劣,必须借助于数理统计方法对其实验数据进行统计处理。 本文叙述了用电位法测定国产K5定向凝固、普通铸造合金分别在700和950℃空气介质中的低周疲劳裂纹扩展速率,以及分别用线弹
Fatigue and fatigue crack growth rate experimental data due to the experimental itself, the material, the measurement error and experimental conditions, environmental and other factors, so that the resulting greater dispersion. In order to quantitatively compare its advantages and disadvantages, it is necessary to make statistical analysis of its experimental data by means of mathematical statistics. This paper describes the potential method for the determination of domestic K5 directional solidification, ordinary cast alloy air circulation at 700 and 950 ℃, respectively, low cycle fatigue crack growth rate, respectively, and the line bomb
